Danlers Limited design and manufacture a comprehensive range of high quality controls for lighting and HVAC including a Heater Boost Switch (pictured).
This simple to use product offers energy saving control for electric heating loads (or other electric loads) such as heater towel rails or electric heaters by automatically switching off the load ensuring it is not left on, wasting energy and money.

Pressing the button selects each time lag option in turn. The load remains on for that chosen time lag before switching off automatically.
The button can be used at any time for selecting a different time lag or for switching off.
